No evidence links man-made global warming to human activity

Upon reading Ursula Rozum's April 20 commentary about global warming, I came away confused, but not surprised. In school, I learned that by using the scientific method, science worked on empirical evidence, not on consensus or theory. I was also taught that all living things emit carbon dioxide, and that Co2 constitutes only about 1 percent of the Earth's atmosphere.

For years we've been told that the political left loves free speech and dissent. Apparently Rozum (like Al Gore, et al.) believes all debate about man-made global warming should end, while ignoring the thousands of scientists who disagree with their theory. Man-made global warming is simply a theory, with absolutely no evidence linking it to human activity.

I am also puzzled at Rozum's omissions of Gore making tens of millions of dollars while promoting environmental issues, and the scandals at green companies like Solyndra. Rozum also failed to mention that a court in Great Britain has ruled that since Gore's ''An Inconvenient Truth'' is so rife with inaccuracies, British schools must show the other side of the global warming debate when showing Gore's film. The environmental movement Rozum promotes seeks bigger government, control by elites, and the ultimate destruction of capitalism. But don't take my word for it. Read the words of leaders of environmental groups like Earth First, Greenpeace and the Sierra Club. Read what Marx and Engels wrote about using environmental issues for political gain. I also urge people to read the works of scientists like Roy Spencer, Brian Sussman and the late Dixie Lee Ray to gain a new or different perspective on global warming and other environmental issues.

As the left owns no monopoly in wanting clean air and clean water, ask yourself why it is almost exclusively them saying we need bigger government to tackle these issues. Please research and question their real motives.
